Sometimes a seemingly trivial task makes the mission become crystal clear. Airmen in the 78th Operations Support Squadron are responsible for keeping the windows clean at the top of the base’s air traffic control tower. It’s imperative to provide a clear field of view for the controllers who direct the aircraft which take off and land here. Once a week, two Airmen walk onto a catwalk outside the tower and use a garden hose and an extended window washing tool similar to a common household squeegee to clean the windows. Senior Airman William Farmer, air traffic control journeyman, performs window-washing duties. (U.S. Air Force photo by Ed Aspera)
